Safety alert issued over tree trimming
SafeWork SA recently issued a hazard alert following an incident in which a tree cutter sustained fatal injuries following a fall from a tree he was felling.
An investigation found the tree cutter was anchored to the same branch as that being used for lowering cut branches which failed under weight.
The weight of the cut branch being lowered possibly outweighed the anchor point branch, while the anchor point for the lowering system was also too far from the main trunk, causing increased loading on the branch.
Safework SA subsequently recommended a number of actions:
Identify hazards for site and tree integrity prior to starting work
Where an assessment of the tree and site has been completed, assess the risks associated with the proposed activity, taking into consideration the method in which the person will be anchored to the tree
Implement control measures to minimise the risks to health and safety
Consider methods of accessing trees: climbing, elevated work platform, suspended work box
Wherever practicable have two points of attachment to a tree
Use a different tree fork or artificial anchor point for the lowering rope and the climbing rope
Ground workers must be in control of the branch being lowered
